* wav – standard audio file container format used mainly in Windows PCs. Commonly used for storing uncompressed (PCM), CD-quality sound files, which means that they can be large in size—around 10 MB per minute. Wave files can also contain data encoded with a variety of (lossy) codecs to reduce the file size (for example the GSM or mp3 codecs). Wav files use a RIFF structure.
* ogg – a free, open source container format supporting a variety of codecs, the most popular of which is the audio codec Vorbis. Vorbis offers compression similar to MP3 but is less popular.
* mpc – Musepack or MPC (formerly known as MPEGplus, MPEG+ or MP+) is an open source lossy audio codec, specifically optimized for transparent compression of stereo audio at bitrates of 160–180 kbit/s.
* flac – Free Lossless Audio Codec, a lossless compression codec.
* aiff – the standard audio file format used by Apple. It is like a wav file for the Mac.
* raw – a raw file can contain audio in any codec but is usually used with PCM audio data. It is rarely used except for technical tests.
* au – the standard audio file format used by Sun, Unix and Java. The audio in au files can be PCM or compressed with the μ-law, a-law or G729 codecs.
* mp3 – MPEG Layer-3 format is the most popular format for downloading and storing music. By eliminating portions of the audio file that are less audible, mp3 files are compressed to roughly one-tenth the size of an equivalent PCM file sacrificing quality.
* aac – the Advanced Audio Coding format is based on the MPEG2 and MPEG4 standards. aac files are usually ADTS or ADIF containers.
* mp4/m4a – MPEG-4 audio most often AAC but sometimes MP2/MP3, MPEG-4 SLS, CELP, HVXC and other audio object types defined in MPEG-4 Audio
* wma – the popular Windows Media Audio format owned by Microsoft. Designed with Digital Rights Management (DRM) abilities for copy protection.
* atrac (.wav) – the older style Sony ATRAC format. It always has a .wav file extension. To open these files simply install the ATRAC3 drivers.
* ra & rm – a Real Audio format designed for streaming audio over the Internet. The .ra format allows files to be stored in a self-contained fashion on a computer, with all of the audio data contained inside the file itself.
* ram – a text file that contains a link to the Internet address where the Real Audio file is stored. The .ram file contains no audio data itself.
* dss – Digital Speech Standard files are an Olympus proprietary format. It is a fairly old and poor codec. Gsm or mp3 are generally preferred where the recorder allows. It allows additional data to be held in the file header.
* msv – a Sony proprietary format for Memory Stick compressed voice files.
* dvf – a Sony proprietary format for compressed voice files; commonly used by Sony dictation recorders.
* IVS – A proprietary version with Digital Rights Management developed by 3D Solar UK Ltd for use in music downloaded from their Tronme Music Store and interactive music and video player.
* m4p – A proprietary version of AAC in MP4 with Digital Rights Management developed by Apple for use in music downloaded from their iTunes Music Store.
* iklax – An iKlax Media proprietary format, the iKlax format is a multi-track digital audio format allowing various actions on musical data, for instance on mixing and volumes arrangements.
* mxp4 – a Musinaut proprietary format allowing play of different versions (or skins) of the same song. It allows various interactivity scenarios between the artist and the end user.
* 3gp – multimedia container format can contain proprietary formats as AMR, AMR-WB or AMR-WB+, but also some open formats
* amr – AMR-NB audio, used primarily for speech
* awb – AMR-WB audio, used primarily for speech
